Abstract
In the basic weld metal, the roll of deoxidizer is very important to obtain sound weld metal. Attempts have been made to obtain weld metals by deoxidation with metallic manganese. Manganese is very weak deoxidizer and its deoxidized products are large particles characterized by its peculiar dendric forms. As results of investigation with analysis of residues obtained by alcoholic-iodine method and its electron diffaaction pattern, its deoxidized products are solid solution of ferrous oxide and manganous oxide.
